Converting 2 Tablespoons of Butter to Olive Oil
For a smooth substitution, the general rule is to use about three-quarters of the amount of olive oil when replacing butter by volume. Given this, 1 ½ tablespoons of olive oil is equivalent to 2 tablespoons of butter. This ratio is critical because olive oil is a pure, liquid fat, while butter is a solid fat consisting of approximately 80% fat and 20% water and milk solids. The higher fat concentration in olive oil means less is needed to achieve the same richness, but it also means adjustments may be necessary for different recipes.
Why the 3:4 Conversion Ratio?
The simple answer lies in the composition of these fats. When you bake with butter, the water content turns to steam, which contributes to the texture, helping to create flaky pastries or an airy crumb. Olive oil, containing no water, offers pure fat. Using a 1:1 ratio would result in a final product that is too greasy or dense. The 3:4 ratio compensates for this difference, providing the right amount of fat while requiring you to account for the missing moisture separately in certain applications.
The Impact of Substitution on Recipes
The effect of swapping butter for olive oil depends largely on the type of recipe. In savory dishes, such as sautéing vegetables or searing meat, the substitution is often straightforward, simply replacing the fat. The choice between olive oil and butter in this context is usually about flavor preference. However, the story is more complex for baked goods.
For recipes that call for melted butter, like some cakes, quick breads, or muffins, using olive oil is generally a safe and effective swap. The result is often a moister, more tender baked good with a slightly denser crumb compared to its butter-based counterpart. The subtle fruity or peppery notes of the olive oil can also add an interesting new dimension to the flavor profile, especially in recipes that pair well with these tastes, like chocolate or citrus.
The conversion is not ideal for recipes that require creaming softened butter with sugar, such as traditional cookies or some cakes. The creaming process is crucial for creating tiny air pockets that give the finished product its structure and rise. As a liquid, olive oil cannot trap air in the same way, leading to a denser texture. In these cases, a 50/50 mix of softened butter and olive oil can be a good compromise to achieve both moisture and structure.
Olive Oil vs. Butter Comparison
| Characteristic | Olive Oil | Butter |
|---|---|---|
| Fat Content | 100% fat | ~80% fat, ~20% water and milk solids |
| Health Benefits | High in heart-healthy monounsaturated fats and antioxidants | High in saturated fat; also contains vitamins |
| Flavor | Varies from mild and fruity to robust and peppery | Rich, creamy, and distinctively dairy |
| Baked Goods Texture | Results in moister, denser, and more tender crumb | Creates a lighter, airier, and flakier texture |
| Best For | Sautéing, dressings, cakes, muffins, and quick breads | Creams, frostings, flaky pastries, and sauces |
| Smoke Point | Generally higher, making it good for higher heat cooking | Lower smoke point than olive oil |
Using the Conversion in Practice
When substituting olive oil for 2 tablespoons of butter, the 1 ½ tablespoon measure is the volumetric conversion. For the best results, especially in baking, a few extra steps can help. For instance, in recipes where some moisture is needed, adding a small amount of extra liquid (like a teaspoon of water or milk) can help balance the oil's lack of water. For savory dishes, the conversion is more flexible, and you can add a little extra oil if needed for browning or flavor.
Remember to choose your olive oil wisely. For delicate baked goods, a mild extra virgin olive oil works best to avoid overpowering other flavors. For savory dishes or recipes featuring bold flavors like chocolate, a more robust variety can add pleasant depth. Proper storage is also crucial to preserve flavor and freshness.
A Final Note on Flavor and Texture
The decision to substitute is often about more than just numbers. While 1 ½ tablespoons of olive oil provides the fat equivalent of 2 tablespoons of butter, the sensory experience will be different. The distinct, sometimes fruity or peppery, flavor of olive oil and the resulting moister, denser texture should be considered part of the result, not a flaw. For many, this is a welcome change that adds a healthier, Mediterranean twist to their cooking. Embracing these differences is key to successful and delicious experimentation in the kitchen.

Conclusion
To substitute 2 tablespoons of butter, you should use 1 ½ tablespoons of olive oil. This 3:4 ratio is crucial for compensating for the pure fat content of olive oil versus the water and milk solids found in butter. While effective for many recipes, particularly sautéing and specific baked goods like muffins, this substitution can change the final product's flavor and texture. For recipes relying on the creaming method for aeration, a partial substitution or different approach is often needed to avoid a denser result. Understanding these nuances allows for a healthier and equally delicious culinary outcome.
